NON-SINKAB LE VESSEL WITH CONNING-TOWER.

Application filed January 12, 1918.

To all whom it may concern:

Be it known that we, JoHAN E. JOI-IAN- NnssnN, JOHAN A. sE'lI-IER, OLAF C. Horn, and CHARLES J. CHRISTLANSEN, respectively, citizens of the United States, residing at Brooklyn, respectively, in the county of Kings, respectively, and State of New York, respectively, have invented new and useful Improvements in l on- Sinkable Vessels with Conning-Towers, of which the follow ing is a specification.

An object of the invention resides in the construction of the hull of the vessel, the same being provided with buoyant air and ballast tanks and cargo compartments which are mutually and collectively related whereby upon the event of one of such parts being destroyed, the vessel will still remain afloat under the buoyant action of the other parts.

Another object of the invention is to provide a ship in which the hull construction thereof is arranged to accommodate from the bow of the vessel to the stern thereof and at both sides, tanks which are adapted to contain a liquid fuel, which may be connected in any suitable well known manner to supply the engine of the vessel with fuel and which also operates to give uniform ballast to the vessel under normal conditions, the said tanks being separable from one another so that should one be penetrated, the next adjacent tanks will not in any way be crippled.

A still further object of the invention is to provide a vessel in which the hull is cons structed of alternately positioned water and air compartments, a compartment for heavy cargo above said water and air compartments and a chain of other compartments, all of which are mutually related with respect to the central line of the vessel so that the vessel can always maintain proper equilibrium under normal conditions, while should any particular compartment of any one of the series mentioned, be destroyed, means can be quickly resorted to, to properly reestablish equilibrium of the vessel.

Another object of the invention resides in the construction of a ship in which full advantage is taken of cargo space to ac commodate a maximum quantity of material and at the same time, provide a structure which will be practically non-sinkable.

Specification of Letters Patent.

Patented Nov. 9, 1920.

Serial No. 211,603.

Figure 1, is side view of the vessel with parts broken away.

Fig. 2 is a vertical section therethrough.

Fig. 3, is a horizontal section on the line 33 of Fig. 2.

Fig-4 is an end view of the vessel Fig. 5 is anend view of the vessel showing a slightly modified form thereof.

Fig. 6 is a detail section therethrough, and

Figs. 7 and 8, are detail views of the base plates of the cargo compartments.

The vessel is provided with a main or top deck 20, underlying decks 21, 22, and 23, an outer bottom 24, and sides 2525. The

sides are curved inwardly at 26, in the direction of the outer bottom 2d, and then outwardly at 27, where they preferably merge abruptly into said outer bottom so that stabilizing channels 2828, are formed in the sides of the vessel at their juncture with the main bottom 24. These channels 'may extend for any suitable distance in the length of the sides of the vessel but in practice, and for other reasons, which will be hereinafter explained, it is found desirable to have same terminate respectively within the stern and bow of the vessel as shown in Fig. 1. By producing these channels 2828, the surfaces 27-27, are made to constitute side balancing keels and the lateral resistance offered thereto by the action of the water, operates to prevent undue rolling of the vessel.

The deck 23, is in effect, a supplemental bottom for the vessel, and as illustrated, it comprises a plurality of substantially identical plates 29, having flanges 30, which are secured byrivets 31, to the T beams 32, which extend all the way from the bow to the stern of the vessel and which are preferably arranged approximately in line with the side balancing keels of the vessel. The said plates are provided with meeting flanges 88 which are riveted together and side flanges 34. The flanges 34:, of the plates come directly against the next adjacent plates and are riveted thereto as shown. At the inner ends, the plates are riveted or otherwise suitably secured to a central keel 35, the base of the latter having permanent connection with the bottom 24, as shown in Fig. 2.

These plates are associated with vertical side plates 3636, which also extend from rivets 31, to the said T beams the bow to the stern of the vessel and as shown, they are provided with base flanges 37, which are secured by the mentio aeld i e upper ends of these plates are riveted at 38, to the side flanges 89, of the deck 22. The latter plate 3636 and said plates 29, mutually define a cargo compartment 40, which is thus disposed directly above the central keel 35, of the vessel. The deck 22, is provided with suitable hatch doors 41, which may be opened in order to permit communication to be established between the cargo compartment 40, and superposed compartments of the vessel.

Beneath the supplemental bottom 23, of the vessel, are vertical cross plates 42, whose inner ends are riveted or otherw'sesuitably secured to the keel 35, and whose outer ends are riveted or otherwise suitably secured to the sides of the vessel, ap-' proximately in horizontal line with the hereinbefore mentioned side keels. The lower edges of theseplates are suitably riveted or fastened by angle-irons 43, to the main bottom .24. Compartments 44, are thus formed between the main bottom '24, and supplemental bottom 23, of the vessel, and in certain of said compartments, water ballast may be provided while in others, air

maybe stored in orderto render the struc ture satisfactorily buoyant. The water ballast may be controlled in any suitable well known manner, in order that the vessel may be lifted or lowered in the water as the occasion'demands. Vi e do not claim any particular 'mechanism for regulating the sup- 40, in which to arrange said superposed compartments 45, whereby the entire area in the hold of the vessel can be fully and properly utilized for storage purposes and at the same time provided with the proper distribution of weight to permit the vessel to maintain its equilibrium in a highly efficient manner.

Other compartments 48, are arranged between the decks 21, and 22, inwhich light cargo is adapted to be arranged. These latter compartments extend from the bulk head 49 to the sides 25, of the vessel. In this manner, full advantage is taken oi the entire area of the ship for the accommodation of light cargo above the compartment 40.

In the form of the invention shown in Fig. 6, the sides 2525, of the vessel are connected to the sides of a supplemental bottom 95, by means of H irons 96, which can be used in lieu of the T beams hereinbefore referred to.

The flanges 33, of said-plates 29, are also riveted to the keel 35, as shown in Figs. 2 and 3..

Cement'97, is filled in between the outer walls of the compartments 45, and side walls of the hull of the vessel and also between the bottom 24, and said compartments 44. A similar arrangement is resorted to between the plates 29, and flooring 98. In this manner, the vessel is nicely balanced and weights distributed so that most beneficial results obtained.

What we claim is A marine vessel embodying a hull including a central keel, side keels, said side keels having their walls curved andmerged into the sides of the hull, a plurality of bottoms connected with said side keels and withsaid central keel, T-beams extending longitudinally of the side keels and connected with the upper bottom, and ballast compartments located at the side of said upper bottom and resting upon said T-beams.

In testimony whereof we afiix our signatures.
